 # 6.6.0 (unreleased)
 
-### Features / Enhancements
-
-* **Graphite**: Add Metrictank dashboard to Graphite datasource
+# 6.6.0-beta1 (2020-01-20)
 
 ## Breaking changes
 * **PagerDuty**: Change `payload.custom_details` field in PagerDuty notification to be a JSON object instead of a string.
 * **Security**: The `[security]` setting `cookie_samesite` configured to `none` now renders cookies with `SameSite=None` attribute compared to before where no `SameSite` attribute was added to cookies. To get the old behavior, use value `disabled` instead of `none`. Refer to [Upgrade Grafana](https://grafana.com/docs/grafana/latest/installation/upgrading/#upgrading-to-v6-6) for more information.
